all my exhaust is 2.5 bonez downpipe, main cat, and magnaflow straight through mufflers, should i put on my stock down pipe? and my airpump and split air thingy? would it pass if i did that?

 

did u have the split air pipe on? Put back the air pump too. It's supposed to blow ait in the main cat.
You won't pass without it.

 

uhh... you kinda need that airpump if im not wrong... and maybe you should try the special additive :P Here you should read this ... http://www.zeroglabs.com/rx7/emissions.htm

 

Hm. You've been running without an airpump & split air pipe? I'm betting your cat is probably toasted. There was someone a while back that failed emissions horribly, put on a new cat of some variety, and passed with flying colors.

how long would it take for the cat to toast?
I've been running my magnaflow cat for a lil less than a week until I found a split air pipe.

 

not too sure of the answer but ... car produces a crap load of heat so im guessing if you drove like less than 5min a day during the week it should be fine :P but i dunno just get a cheap cat replacement and hook up the airpump :P
